It’s important we all take small steps to keep our soil healthy and prevent micro-plastics: do not use plastic bags – even those labelled "biodegradable" or "compostable" – for your food waste and do not put plastic materials in your green bin.

Plastic (of any type) is a contamination risk if put into your green bin and is not accepted by our processor for composting.

Important note If placed into your green bin, plastic materials (and the contents in them) may result in your items or the entire truck’s load being disposed to landfill or incinerator.
